Astronomers now routinely discover planets orbiting stars outside of the solar system. The best chance astronomers have of finding life on another planet is likely to be on a super-Earth. Super-Earths are more massive than Earth but smaller than ice giants like Uranus and Neptune.

It would also have oceans that are shallow enough for light to stimulate life all the way to the seafloor and an average temperature of 77 degrees Fahrenheit.Read Long Article
